Y yThisjwall 17' `istitted against the periphery ot' the Wheel and extendsl from the,A spout 201i each sidelof a chamber 14 Whenit 'is in thereceiviiig posi- Y vtion and serves to cut off the supply of material fromthe hopper 11 as each `Vch'aiiifl ber aan@ aes@ all. E9e? 14 leaves the receivingposition, and' it' i; evene Vcarried by a horizontal shaft 18 which extends through the Wallsof the hopper 15 and Lsupports the same, andvivhich is litted to turn in suitable bearings n the standards 4. The hopper is additionally supported by the frame bar 5 to which it is'secured. rfhe shaft 18 is provided With a ratchet Wheel 19 havingteeth Which correspond in number `With the measuring chambers 14 and Which are adapted to be. engaged by a reciprocative, spring pressed, pin or pawl 2O fitted to Work Within a guide opening in an arm 21 which is pivoted at one end on the shaft 18. rlhe other end of the arm 21 is connected by a pitman 22 to the vupper end of an arm 23 Whose `lower end ispivoted on a shaft 24 which extends between and is supported by suitable bearings on the standards 4. YThe arm 23is connected by a pitmanr25 to a crank 26 on the inner end portion of a shaft 27 'which is fitted to rotate in a bearing 28 on one'of'the standards.' rhe ratchet Wheel 19 and its pawl 2O and parts connecting the paWl carrying arm 21 and crank 26 are `arranged to move the arm 21 back and forth and cause the measuring wheel 13 to be rotated step by step When theshaft 2 7 isY rotated, turning the measuring Wheel a quarter revolution, or one step, each time the shaft 27 is turned a complete revolution.

The outer end portion of the shaft 27 has a sprocket Wheel 29 loosely mounted thereon and adapted to -be `driven constantly by a chain 30'passing around the same and a similar Wheel 31 on a shaft 32 which turns in bearings on thestandards 4. The shaft 32 is driven by a chain and sprocket connec- .tion 33 with a shaft 34 which turns in a bearing on one of the 'standards 4 and which is provided With a pulley by means of which the shafts 34 and 32 may be driven constantly from a suitable motor or source of power.

The sprocket wheel 29 is provided With an annular flange 36 which extends laterally eewhch is connected'by a spring 45 to. the

arm 39. The spring 4 5 acts tov press the lever @11142twardthenner Surface 0f .th

aange 36, sotliat, when' the lever 42 is free to move in that direction, the arm' 42 Will enter oneof the notches 37 of the flange 36 and cause the collar 38 and shaft 27 to rotate c With the sprocket Wheel 29, until the lever' 41 is moved against the action of thekspring 45, as hereinbefore explained, yto disengage the Varm V42 from the notch 37 in the flange Y 36, Whereuponthe shaft 27 Will cease to rotate, and the sprocket Wheel 29 willr turn 'idly thereon.

Ful'cruined, at 46, on a bracket on one of the standards 4 is a lever 47 having an arm 48 provided on its free end With a hook'49 Which is adapted to engage the clutch lever arm 43 and which rests upon the sprocket Wheel flange 36 when the clutch lever 41 is rotating With the sprocket Wheel 29. lVhen the hook 49 is engaged Vvviththe clutch lever arm 43, as clearly shown in Fig. 6, the lever arm 42 is held away fromthe notches 37 in the rotating flange 36; and', when it is desired to actuate the shaft 27 by the sprocket Wheel 36, the lever 47 is raised to disengage the hook 49 from the clutch lever arm 43 and permit lthe spring 45 to move the, lever arm 42 into engagement With one of the flangenotches 37, causing the shaft 27 to be rotated by and With the sprocket Wheel 36. After the lever 47 has been raised to start the rotation of the shaft 27, itis permitted to drop byL gravity and -rest upon the ange 36 until its hook 49 is re-engaged by the lever arm 43. lV hen thev lever arm 43 re-engages Y thehook 49 the lever arm 42 is moved from engagement vwith a notch 37 in the fla-nge 36 and therotation of the shaft 27 is stopped after it has been turned a complete revolution by the sprocket wheel 29.

It Will now be understood that the lever 47 and its associated parts forms a trip device Which may be operated or' raised by hand or by suitable mechanism to free the clutch lever arm 43 and then released to free the lever 47 and permit its hook 49 'to rest upon the flange 36, and that each time the clutch device is thus operated the shaft 2,7 Will be turned one complete revolution by the constantly .rotating sprocket Wheel 29. It `will also be understood that each time the trip lever is operated, theturning of the shaftv 27 vvill turn the crank 26 one complete revolution and thereby't'urn the measuring Wheel 13 one step, causing one of its chainbers 14 to receive a charge 'of material from the hopper 11, and causing one of its chambers 14 to discharge its contentsr into the hopper 15. as measured quantities of' material Vfrom the hopper 11 are thus successively discharged from the chambers `14 byl succes-3- sive operations of the trip lever` 4,7, the measured quantities o f material are successively received by and discharged from the hopperl `through its spout :1.6; and ioi" oi material from'v the` hopperv 15,a `suitable receptaclePor-carton 50' is placedbeneath the spout i6 to receive the material. "The "receptacles -50 maybe placed'r beneath the spout 16. by handy orthey may be placed in spaced relation upon a suitable cha-in or. carrier 5l which may be operated intermittently by hand or by 'power to move thev cartons into and from the `charging station beneath the spout 16, permitting` each carton to rest at the chargingstation long enough to receive a charge of material. Thecarrier v5l is lit-ted toy slihdein guideways iin parallel bars 52 which are mounted on a table 53 `which is suitably supportedforwardly of the standardsf4. Thecarrier 5l is provided 'withY spaced pairs'of upwardly projecting plates 54 between which the cartons 50 are placed by hand. 'f Y 'f lVhen the carrier 51 is employed to move the cartons 50successively-'to the'charging station, l utilize the V'carrier 5l to operate a table 53 is a post'56 forming the ulcrum/ mechanism Which automatically operates the 'triplever 47 each time a. carton is' moved into the charging station-, as follows: liro-l jecting" upwardly from a bracket 55 on the of a horizontal-lever V57 supported on'the upper end-of Vthe post.` The torivardarm"VV ot the lever 57/ extends-into the4 pathv of the carrier plates' 54, and the rearwardarm of the lever 57 is pivoted to oneend portion of a light bar 58. vThe other end portion of the bar 58 rests upon a lug 59 von a lever 60 and is held in pla-ce .thereon betweeny the body of thelever 60 and ajprojection'tl thereon.v The bar 58 is" provided `with av tooth 62 whichis adapted Vto 'engage'the lug 59 and move the lever 6() With' the bar 58.' The lever 60 is pivoted, at`63, to a bracket 64 on one of the Vstandards 4 and it is provided Vwith a' projection 65 lwhich is connected byV a link 66-to the forwardly projecting a'rrn 67 ot' the triplever 47. Each time'the carrier5l is operated to Amove a carton 50 into the charging station a. pair of carrier platesV 54 1s moved past the forward arm of the lever 57,' and when' the carrier v5l isthus operated, the plates 54 engage the lever 57 and causefitto operate the bar lever-60 and link to' raise the trip lever 47 to Ytree lthe clutch lever 41, and', immediately thereafter, the part 59a engages abar 58 `and raises its tooth 62 from the lug 59 and permits the trip levr'47'todrop by gravity and rest uponthe sprocket Wheel Harige 36. Then the tooth 62 escapes the lug 59, the lever 60 dropsback by gravity against a stop68 projecting froman arm 69 on Vthe bracket 64: and, after the lever 57 escapes the pair of carrier plates t-moving vpast it, a spring 7G encircling the post 56 and r havingone end engaged'vvith the lever 57 and the other end engaged with a collar on the Post 5,returns the lever 57 tonormal `jacent to the Wheel 74.

' Mounted toturn in bearings on the standards 4 is a rock shaft 96 having an arm 108 shortroclr shaft 111 Which turns in a bracket on one of the standards 4 so that When-the shaft 96 Vis rocked, the shaft 111 will be rocked also. The shaft 111 carries an arm 97 provided on itsV free end Vwith a hook 98 which is adapted to engage the clutch lever arm 98 and which restsv upon the sprocket Wheel. flangey 86 when `the clutchflever 91 is rotatingvvith the sprocket Wheel 74. Adjacent to the arm 97 is a longitudinally movable plate 99 guided and supported by the shaft and a pin 100 projecting from the arm 97 and into a slot 101 in the plate 99. One end of the plate 99 has a. hook 102 thereon which is adapted to engage the lever arm The plate 99 is movable longitudinally of the arm 97 and it is held normally in the position shown in Fig. 9 by a spring 108 having one end attached to the plate 99 and the lother end attached to a screw 104 carried by an arm 105 projecting from one of the standards 4. The spring 108 holds the hook 102 normally spaced a slight` distance from vthe hoolr'98 and the plate 99 is movable against the action of the spring 108 to bring the hooks 98 and 102 into registry.

In the normal position ofthe parts, as shown in Fig. 9, the hook 102` is engaged i' with the clutch lever arm 98 and the lever arm 92 is thereby held away from the notches 87 in the rotating flange 86; and, when the shaft 9G is rocked to raise thel arm 97 and hook Y98 and therewith the plate 99 and hook 10,2 from the flange 86, the'spring 95 is permitted to move the lever arm 92 into engagement with one of the lia-nge notches 87, causing the shaft 7 5to be rotated by and with the sprocket Wheel 74. After the arm 97 and plate 99 have been raised to start the rotation of the shaft 75, they are permitted to drop'by gravity andrest upon the flange 86 until the hooks 98 and 102 are engaged by the lever arm 98. `When the lever arm 98 engages the hooks 98 and 102 it moves the hook 102 against the action of the spring 108 until the arm 98 is stopped by the hook 98 and the hook .98 then causes the lever arm 92 to move from engagement with a notch 87 in the flange 86 and stop the rotation of the shaft after it has been turned a complete revolution by the sprocket Wheel 74. After the rotation of the shaft 75 has been thus stopped, the spring 108, being stronger than the spring 9 5, moves the hook ,1102 back from the hook 98 to the position shown in 9 and Athereby moves the lever arm 92 from actual contact `With the flange. 88 'and prevents the noise which would occur if the parts cnnected to the shaft 7 5 were permitted to holdtthe arm 91 inv engagement with the `flange 86.

an arm 106 which rests in the path of ank arm 107y carried by the normally'idle shaft 27, which is controlled by the trip lever 47 hereinbefore described. Thearms 106 and 107 are sorelated that just before the shaft 27 completes each revolution, after being set in motion by the operation of the trip lever 47, the armA 107 engages the arm 106 and rocks'the lshaft 96 and raises the hooks 98 and 102 from the clutch lever arm 98 and thus starts the. rotation of the shaft 75 and, immediately thereafter, theA arm 107 `escapes the arm 106 and permits the arm 97 to drop back by gravity until the hooks 98 and 102 rest upon the Flange 86 to engage the lever arm 98-and stop the rotation of theV shaft 75 after it has been turned a. complete revolution, as previously explained.

It will now be understood that the arm 106 and parts operated thereby form a trip device which is under the control ofthe trip lever 47 and which is operated autofA matically to rotate thestirrer 84 for a limchambers 14 of the measuring Wheel 18 is in the receiving position inv registry with the spout 12 to ensurethe filling of the cham'- bers fromV the hopper 11.
